Wu Shuo learned that the official statement from Ekubo Protocol was released. After the Huff Router vulnerability incident, to prevent users from suffering losses in the future due to unrevoked ERC20 risk approvals, the team carried out a white-hat operation, protecting approximately $284k in potential funds. Ekubo deployed a rescue contract that provides users with token flash loans, prompting the vulnerable router to automatically use the user's authorized limit to repay the loan. Ekubo stated that this operation does not require active user participation and has essentially eliminated the remaining authorization risks in the three vulnerable mainnet router deployments.
